I'd be here all day, but I will say that judging by what I gather of your music tastes you will likely not enjoy any of the bands listed so far except Liquid Tension Experiment, whom I know you are already familiar with. For you to start I recommend Canvas Solaris' "Penumbra Diffuse" highly, I can even send it to you if you'd like

I'll look into them and Pelican thanks!

Edit: Canvas Solaris seems cool! I can't find any samples from "Penumbra Diffuse" but "Sublimation" sounds good! Do you know if the two albums are very different?
